T3 · Circuit locker · private link, no account
Your boat's whole panel, sized and labelled.
A locker is one boat's circuit schedule: every circuit with its position, current and run, the wire size and fuse ceiling worked out for each, and labels ready to print. The link is the only key, so keep it somewhere safe.
| Pos. | Circuit | Amps | Run | Wire | Fuse ≤ |
|---|---|---|---|---|---|
| A1 | Navigation lights | 1.8 | 22 ft | 16 AWG | 37.5 A |
| A2 | Bilge pump | 7.5 | 18 ft | 10 AWG | 90 A |
| A3 | Cabin lights | 3 | 15 ft | 16 AWG | 37.5 A |
An example of what a locker shows (12 V, 105 °C cable, 3% drop for the first two and 10% for the cabin lights). Each row is computed with the same rules as the wire check.
- Nothing about you is stored: no name, email or location. Just the circuits you type.
- Lockers nobody opens for 400 days are deleted. You can delete yours at any time.
- One locker per panel works well: open a second for a second panel or another boat.
